A senior police officer is on paid administrative leave after exchanging gun fire with a suicidal man early Thursday morning, police say.

Senior Police Officer Dustin Wing has been with Des Moines police for 13 years, according to a Des Moines poilce news release. He is also a K-9 handler. Placing him on leave is standard procedure, police say.

The suspect in the investigation is still hospitalized for observation. Once he is released, charges are expected, according to the release.

An early morning police chase with the 21-year-old ended after the man and Wing exchanged gunfire.

At about 12:50 a.m. Thursday, police received information about a suicidal man armed with a pistol. The man fled in a vehicle after he was located about an hour later near 31st Street and Interstate Highway 235, according to the release.

Police pursued the man through Des Moines, onto the interstate and to northbound Interstate Highway 35. The chase ended near mile marker 108 after deputies with the Story County Sheriff's Office deployed stop sticks.

As the man's vehicle slowed, he fired more than one round from the pistol, according to the release. Wing returned gunfire. No one was injured by the gunfire.

After the vehicle stopped and a short standoff, the man threw his gun from his vehicle and surrendered to police.
